Log message:
libnbcompat-20090322:
Don't use getopt_long as replacement for getopt. It behaves different
and doesn't work well in combination with optreset. Instead use
getopt(3) from NetBSD if requested. Sync getopt_long.c with NetBSD while
here. Addresses issues with pkg_admin on Solaris reported by Tim Zingelman.

Log message:
libnbcompat-20090302:
Add TAILQ_LAST.

Log message:
Provide TAILQ_FOREACH_SAFE if it is missing.

Log message:
Fix PR 40151 - bootstrap of pkgsrc fails on Ubuntu 8.10
- At least Ubuntu 8.1 sets __attribute__((warn_unused_result)) on fwrite()
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25509
  which means (void)fwrite(...) will *always* generate a warning, so
  set -Wno-error to bypass this in Linux.sys.mk
- Ubuntu 8.1 also jumps through hoops to ensure ARG_MAX is *undefined*, so
  work around this in tnftp and libnbcompat

Log message:
Only use issetugid if it exists. Fixes reported build issues on QNX and
AIX.

Log message:
Need to include stdint.h for unit64_t on SUA 6.0.

Log message:
OpenBSD headers are still not standalone, even though SUS is pretty
explicit about it at least for netinet/in.h. Include sys/types.h before
checking for content of sys/socket.h and netinet/in.h to fix this.
Reported and tested by Georg Schwarz.

Log message:
Add some forgotten ifndefs to fix issues on DragonFly.

Log message:
Define __UNCONST. From PR 39797.

Log message:
Avoid STAT as macro, it exists in sys/dir.h on AIX already.
